About
Keyword Tool is an online keyword research platform that uses Google Autocomplete and 15+ other platform autocomplete systems to generate long-tail keyword suggestions for SEO, content creation, and PPC advertising. The free version generates up to 750+ keyword suggestions per search without requiring an account, while the paid Keyword Tool Pro tier adds search volume, CPC, competition data, bulk upload, and API/MCP server access. It supports 190+ Google domains, 120+ languages, and 68,000+ geo locations for international SEO research.
Problem
Marketers need to discover the actual keywords their audience uses across search platforms, but Google Keyword Planner hides profitable long-tail keywords and requires a Google Ads account.

How it works
The tool prepends and appends search terms with letters and numbers, queries Google and 15+ other platform autocomplete APIs, and returns keyword suggestions along with optional search volume and CPC data for paid users.
